CVE-2025-68031 is a reflected Cross-site Scripting (XSS) vulnerability identified in the faraz sms professional SMS plugin (افزونه پیامک حرفه ای فراز اس ام اس), affecting versions up to and including 2.7.3. The vulnerability stems from improper neutralization of user-supplied input during web page generation, which allows attackers to inject malicious JavaScript code into web pages viewed by other users. This reflected XSS occurs when crafted input is immediately included in the HTTP response without sufficient sanitization or encoding. An attacker can exploit this by tricking a user into clicking a malicious link or submitting specially crafted input, causing the victim's browser to execute the injected script. Potential consequences include session hijacking, credential theft, unauthorized actions on behalf of the user, or redirection to malicious websites. Although no public exploits are currently known, the vulnerability is publicly disclosed and unpatched as of the publication date. The affected plugin is a specialized SMS messaging extension primarily used in Persian-language web environments, suggesting a limited but focused attack surface. The absence of a CVSS score requires an independent severity assessment. Given the nature of reflected XSS, the vulnerability impacts confidentiality and integrity of user data, is relatively easy to exploit without authentication, and can affect any user interacting with the vulnerable web interface. The plugin's usage in countries with significant Persian-speaking populations and web presence increases the risk in those regions. Mitigation involves applying patches when released, implementing rigorous input validation and output encoding, and deploying Content Security Policy (CSP) headers to restrict script execution. Monitoring for suspicious activity and educating users about phishing risks can further reduce impact.

The primary impact of CVE-2025-68031 is on the confidentiality and integrity of user data accessed via web applications using the faraz sms plugin. Successful exploitation allows attackers to execute arbitrary JavaScript in the context of the victim's browser, potentially leading to session hijacking, theft of sensitive information such as cookies or credentials, unauthorized actions performed on behalf of the user, and redirection to malicious sites. This can erode user trust, damage organizational reputation, and lead to further compromise of internal systems if administrative users are targeted. The vulnerability affects any user interacting with the vulnerable web interface, expanding the scope of impact. Although availability is less directly affected, secondary impacts such as defacement or phishing can disrupt normal operations. Organizations relying on this plugin for SMS functionality in their web applications face increased risk of client-side attacks, especially if they have high-value or sensitive user bases. The lack of known exploits in the wild currently limits immediate widespread damage, but the public disclosure increases the risk of future exploitation attempts. The impact is particularly significant for organizations in regions where this plugin is widely deployed, as attackers may focus on localized targets with higher success probability.

1. Monitor the vendor's official channels for patches or updates addressing CVE-2025-68031 and apply them promptly once available. 2. Implement strict input validation and output encoding on all user-supplied data to prevent injection of malicious scripts. Use context-aware encoding libraries to sanitize inputs before reflecting them in web pages. 3. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 4. Conduct regular security audits and code reviews of the plugin and any customizations to identify and remediate similar vulnerabilities proactively. 5. Educate users and administrators about phishing and social engineering risks associated with reflected XSS attacks to reduce the likelihood of successful exploitation. 6. Employ web application firewalls (WAFs) with rules tuned to detect and block common XSS attack patterns targeting the plugin. 7. Limit the exposure of the plugin's web interface to trusted users or networks where feasible, reducing the attack surface. 8. Maintain comprehensive logging and monitoring to detect suspicious activities indicative of exploitation attempts. 9. Consider alternative SMS plugins or solutions with stronger security track records if timely patching is not feasible.
